Patent number: 10870203Abstract: A machine tool control device and a production system are provided which determine an operation sequence of a robot and set numerical data required in operation, by setting the selection of an operating program of a robot, and/or setting of operations of the operating program, based on an instruction by the user from the machine tool side. A numerical control device which is connected to a robot control device for controlling a robot and controls a machine tool that is used in combination with the robot, includes: a reception unit that accepts setting information for the robot; and a sending unit for sending a parameter setting a selection of an operating program of the robot, and/or setting operations of the operating program, based on the setting information accepted by the reception unit.Type: GrantFiled: April 17, 2018Date of Patent: December 22, 2020Assignee: FANUC CORPORATIONInventors: Yoshihiko Tarui, Yoshitsugu Ogawa, Yoshinori Hoshino

Patent number: 10416650Abstract: Since a data acquisition condition setting unit can select a data acquisition start/end trigger, a sampling period of data, and a type of acquired data, a waveform display device, which has a function of allowing only necessary data to be acquired by allowing a plurality of data acquisition conditions to be set with respect to one data acquisition, can set these conditions from a screen of a data acquisition condition setting. When data needs to be acquired according to a plurality of different conditions, a plurality of types of necessary data acquisition conditions is set to set different data acquisition condition names. When a plurality of data acquisition conditions is set by acquiring data once, a multi-data acquisition condition setting unit can set necessary data acquisition conditions using a screen of a multi-data acquisition condition setting.Type: GrantFiled: April 7, 2016Date of Patent: September 17, 2019Assignee: FANUC CORPORATIONInventor: Yoshitsugu Ogawa

Patent number: 10317871Abstract: A machine tool system and an opening stop position calculating device are provided. The machine tool system includes an openable and closable door for closing an opening of a cover surrounding a machine tool. Furthermore, the machine tool system includes an opening width setting unit for setting an opening width of the door, an opening stop position calculating unit for calculating an opening stop position of the door at which a total time, which is obtained by summing a time required to move the door from a fully closed position to a position of the set opening width and a time required to move the door from an opening stop position where the door is opened and stopped to the fully closed position, is minimized, and a door control unit for controlling opening and closing of the door based on the calculated opening stop position when exchanging the workpiece.Type: GrantFiled: March 15, 2017Date of Patent: June 11, 2019Assignee: FANUC CORPORATIONInventor: Yoshitsugu Ogawa

Patent number: 9527176Abstract: A rotary table is rotated by a machining load. A drive motor tries to return the rotary table to a positioned target position, and increases output torque. When the output torque reaches upper limit torque Tmax or when output torque which is equal to or greater than permissible torque Tp continues for predetermined time ?T, a target position which is sent to a drive motor is changed, thereby promoting reduction in output torque. If the output torque becomes smaller than permissible torque Tp, the target position is changed to bring position deviation of the drive motor equal to 0, and the position deviation is swiftly returned.Type: GrantFiled: October 21, 2014Date of Patent: December 27, 2016Assignee: FANUC CORPORATIONInventor: Yoshitsugu Ogawa

Publication number: 20160103444Abstract: A controller performs tool indexing operation by controlling a tool post driving motor that drives a tool post that can house a plurality of tools and can position a desired tool to a specific position. At this time, the controller estimates an amount of movement of the tool post driving motor based on the number of a tool pot at a tool change position at the start of tool indexing operation and the number of a tool pot that houses a tool specified to be changed. The controller compares the estimated amount of movement of the motor with an actual amount of movement of the tool post driving motor in tool indexing operation, and thereby detects an abnormality in tool indexing operation.Type: ApplicationFiled: October 7, 2015Publication date: April 14, 2016Inventor: Yoshitsugu OGAWA

Publication number: 20130338815Abstract: A numerical controller for controlling a machine tool includes a display which displays a virtual control panel composed of an operation key for operating a machine and a lamp indicating operating information of a machine. A plurality of components (buttons and lamps) of each virtual control panel are defined. Each virtual control panel composed of the defined components is associated with a command code to be given by an NC program, and whether to display or hide the virtual control panel is set. When an NC program is executed, and a command code is read, a virtual control panel corresponding to the command code is displayed or hidden.Type: ApplicationFiled: April 18, 2013Publication date: December 19, 2013Applicant: FANUC CorporationInventors: Yoshitsugu OGAWA, Susumu MAEKAWA
